HENRY M. LUTZ, OF NEW YORK, N. Y.

\ Application filed April 13,

i To all whom it may concern:

Be it known that I, HENRY M. LU'rz, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Glazing-Clip, ofwhich the following is a full, clear, and exact description.

This invention relates to means for attaching plates of glass or thelike to metallic bars such as are commonly used in the makin of sklights or windows for factories or ot er bui dings.

Among the objects of the invention is to provide a skylight constructionfor modern reproof factory buildings in which window lights or platesare supported upon thebase flange portions of T-rails or theirequivalent, the arrangement being such that the plates are secured inthe most reliable manner and with the least possible loss of time.

Another object of the invention is to provide a skylight or roof rail inthe form of a T-beam having formed through or in the web portion thereofa series of holes or notches and with which the flexible tongue ortionof a clip is adapted to engage and interlock, while the end or footportion of the cli bears firmly against the outer surface 0 the plate.

A still further object of the invention is to provide a clip forsecuring the glass plates in place with respect to the metal angle orT-rails, said clip being designed to be secured in place by the simplestpossible direct movement thereof over the free edge of the rail web. I

With the foregoing and other objects in View the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the-exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to theaccompanying drawings, in which like reference characters designate thesame parts in the several views, and in which- Figure 1 is a verticaltransverse section on the broken line 11 of Fig. 2.

Fig. 2 is a longitudinal section of one of the window plates andindicating the T-rail and clip in side elevation.

Fig. 3 is a side elevation of a fragment of the rail indicating adepression formed in or through the web thereof.

GLAZING-CLIP.

Patented July 19, 1921.

1920. Serial No. 373,653.

- Fig. 4 is. a vertical transverse sectional detail indicating a slightvariation in the formation of the T-rail.

Referrin now more specifically to the drawings show a rail 10 havingbase flanges 11 and a web portion 12 arranged at right angles to thecentral ortion of the base in the usual manner. *ormed in or through theweb 12 are any suitable number of holes 13 made by any suitable meanssuch as by punching or drilling, and of any suitable slze or form. .()ras 1ndicated in Fig. 4: the web 12 may simply be provided with notchesor depressions arranged opposite each other in pairs as indicated at 13'whereby the rail Wlll maintain approximately its full strength. Suchnotches may be of any suitable form, but with their upper edges lyin inthe same plane approximately perpend icular to the plane of the web andso have the same effect as the hole 13.

The glass plates G may be supported upon the flanges 11 in any suitableor well known manner, preferably upon cushions 14.

My improved clip is shown as comprising a curved ortion 15 embracing thefree edge of the we 12 and having oneither or both sides of the web legportions 16 terminatin in outwardly flared and slightly upturne feet 17which bear directly against the outer surfaces of the glass. As shownthe curved portion 15 of the clip is approximately U-shaped and conformsclosely to the form of the edge of the web. Each leg portion 16 isprovided with a tongue member 18 formed in any suitable manner from themain portion of the clip as by means of punching or stamping, and sincethe cli is preferably made of some suitable fleXi le sheet metal,

or its equivalent, the tongues 18 are somewhat more resilient than theremaining portions of the clip. Each tongue is integral with the footportion of the clip and otherwise free to be bent inward toward theopposite tongue. In the manufacture of these clips they are made toassume substantially the position or form shown in Fig. 1 wit the pointsof the tongues bent inward some what toward each other while the side ormain portions of the legs lie to a large ex tent parallel to the sidesof the web.

The application of the clips to the rails is a very simple one. Theglass plates having been put in place as aforesaid the operator simplyapplies the clips over the web 12 of the rails at as many points as arenecessary i' tive space between or desirable, each clip being forceddirectly over the free edge of the web, over the holes or notches. Thisoperation may be performed by hand or by any suitable forcing tool, andthe tongues 18 snap into the holes or notches as shown in Fig. l.Inasmuch as the leg portions of the clip are slightly fiexi ble itfollows that with theclips and rails made in accordance with anybuilding specification and corresponding to the thickness of the platesand cushions, obviously any slight variation that may occur in theeffecthe plane of the outer surface of the plates and the outer edge'ofthe holes or notches will be compensated for by'the resiliency orflexibility of the leg and foot portions of the clips. When the points etongues once'sna into the notches or holes the clips are sel -retainingand hold the plates firmly in place. The device is unusually. simple inconstruction and operation and has superior holding qualifications. Itis impossible for the device to become loose or fail to hold, and yet ifit is desired to be removed it can be done by the use of a tool appliedbeneath one or the other of the legs causing such legs to be bentoutward far r enough to release the tongues from the holes or notches.

I claim:

1. A glass securingmeans comprising in combination with a T-shaped bar,the web of which is provided with cut-out portions, a U-shaped resilientclip, the free ends of the legs of which are flared outwardly to provideglass-engaging feet, and resilient tongues formed in the body portion ofsaid U-sha 36d clip, the free ends of said tongues being adapted toengage within the cut-out portions of the web of the bar to maintain thefeet in contact with the glass and the U-shaped clip in position uponthe web of said bar.

2. A glass securing means comprising in combination with a glasssupporting element having cut-out portions, a U-shaped clip of resilientmetal, the free ends of which are flared outwardly to provideglass-engaging feet, and resilient tongues formed on opposite sides ofthe U-shaped member and having their free ends pro ecting forwardly ofthe body portion of the U-shaped member and adapted to be receivedwithin the cut-out portions of the glass support to maintain the glassengaging feet of the U-shapcd member in engagement with the glass toretain the same in position on said support.

3. In combination with a glass and its support, glass securing meanscomprising a U-shaped member, the free ends of the legs of which areflared outwardly to provide glass engaging feet, and oppositely dis)osed resilient tongues, the free ends of which are positioned inwardlyof the body portion of the U-shaped member and adapted for engagementwith the support to maintain the U-shaped member in position on thesupport and the glass engaging feet of the le s of the U-shaped memberin contact wit the glass.
